“…The result is consistent with the preceding obtained results given in Figure 6. This is also in line with the previous literature reported by Porteiro et al, [8] and Dramane et al, [21] that an increase in voltage leads to an increase in ESP particle collection efficiency. As a result, the quality of humid air that will be condensed is better, generating clearer and more potable water.…”

“…There are several factors that affect ESP performance such as types of collecting electrodes, geometric, electrode material, air/gas flow rate, collector voltage, etc. The effect of voltage on particle collection efficiency has been investigated in previous studies such as that conducted by Porteiro et al, [8]. This research estimated the dust collection efficiency of small-scale ESP using simulation software and found that the increase in voltage causes an increase in particle collection efficiency.…”

Humid air as a source of water can be utilized by using a condensation system called the Atmospheric Water Maker (AWM) in order to overcome the problem of limited drinking water supply. However, to maintain water quality and production capacity, the AWM requires an air filtration system with minimum flow resistance. In this work, an electrostatic precipitator (ESP) was used as an air filter for AWM application. Thus, this study aimed to investigate the performance of ESP in terms of particle collection efficiency and water quality produced by AWM. In order to evaluate the performance of ESP, wire to cylinder type ESP was designed and three experimental activities were performed i.e., smoke filtration test, dust filtration experiment, and AWM water quality assessment. The performance of ESP was studied at various voltages ranging from 5.8 kV to 9.7 kV and two wire mesh sizes. The results showed soot particles were successfully removed by the ESP for all applied voltages with both 1 mm and 4 mm wire mesh. The effect of ESP voltage could be observed in dust filtration experiments in which the particle collection efficiency increases with the increase of voltage. The highest particle collection efficiency was observed at a voltage of 9.7 kV with a wire mesh of 1 mm. The results also showed that the use of ESP for AWM application offered a positive effect on the quality of condensed water in which the water physical and chemical properties satisfy the WHO standard for drinking water.

“…A consequence of the fast electron attachment in the cathode immediate vicinity assumed in the models ( [242,244,245] and many others) is that the rest of interelectrode space is supposed to be filled solely with negative ions. On the other hand, there is a strong experimental evidence for a significant density of free electrons in electrostatic precipitators and other practical devices based on the negative corona charging process several cm away from the cathode [249][250][251]. Such free electrons can be efficient particularly in charging nanoparticles [252,253].…”

The review provides an up-to-date overview and discussion of phenomena related to positive streamer breakdowns in short uniform and non-uniform field (corona) gaps. The terminology used to specify different types of streamer phenomena is critically discussed in light of a unified theory of high-pressure gas discharges describing the sequence of ionization events from initial electron avalanches up to a partial or complete breakdown. The emphasis is given to the understanding of the formation of an active cathode spot by the streamer arrival to the cathode, which is the critical but still obscure phase of the breakdown development. Based on the analysis including a computer simulation model a hypothesis is advanced that also such widely studied and practically important gas discharge phenomena as negative corona Trichel pulses and fast ionization instabilities in cathode regions of high-pressure gas discharges are due to the formation of positive streamers in the immediate cathode vicinity. The proposed hypothesis offers attractive feature of the unification of a wide scale of high-pressure gas discharges within the general class of positive streamer initiated breakdown phenomena. Moreover, it provides indications for further study in the field both by experiment and computer simulations.

“…A recent report from the United States Environmental Protection Agency has shown that 2.1 million deaths are incurred every year due to the rising concentrations of PM 2.5 worldwide 5 . Therefore, to eliminate PM 2.5 from polluted air, various technologies including electrostatic precipitation 6 7 8 and electrostatic enhanced fiber filtering 9 , have been exploited. Both of these techniques can effectively adsorb particles due to fortissimo electrostatic force.…”

Fabrication of air filtration materials (AFM) that allow air to easily flow through while retaining particles is a significant and urgent need due to the harmful airborne particulate matter pollution; however, this is still a challenging research area. Herein, we report novel slip-effect functional nanofibrous membranes with decreased air resistance (reduction rate of 40%) due to the slip flow of air molecules on the periphery of nanofibers. This was achieved through careful control over the diameters of electrospun polyacrylonitrile fibers and aperture size of fiber assembly. Fiber assembly with 86% of fiber diameters between 60–100 nm was found to be most effective for slip flow, as these diameters are close to the mean free path of air molecules (65.3 nm). Significantly, an equilibrium factor τ = df/d2 has been introduced to elucidate the effect of distance of adjacent fibers on the drag force of airflow. Furthermore, the most effective aperture size (>3.5 μm) for slip-effect has been determined. Ultimately, the new material displayed low air resistance of 29.5 Pa, high purification efficiency of 99.09%, good transmittance of 77%, and long service life. The successful fabrication of such materials can facilitate the development of high-performance AFMs for various applications.
